GitHub action

[kylegranger]

There is a new CI for polkadot-light-client. It employs the deploy key strategy first used in libp2p to clone private repositories. It also makes use of a cache for conan data. After you build the first time, you will see these cache items.

% gh actions-cache list
Total caches size 777.12 MB
Showing 2 of 2 cache entries in eqlabs/polkadot-light-client
gcc-plc-conan-data    422.22 MB  refs/heads/github-action  12 minutes ago
clang-plc-conan-data  354.90 MB  refs/heads/github-action  18 minutes ago

You can trigger the build by using this gh command, from the command line while in the repository.

gh workflow run 'Build' --ref github-action

If it gives you two choices, choose Build from build-ci.yml. Github caches these commands in a way that is not completely transparent to me.

When I try to run cmake -DPACKAGE_MANAGER=Conan .. I'm stuck in cloning soralog:

thanks for that catch.. the default github host is getting overwritten by an empty string, when getting sent to the libp2p cmake, and none defined in the original plc cmake command line

[GraDKh]

Yes, you can just add set with CACHE and the default value defined

[kylegranger]

I think I just missed setting setting values for soralog and sqlite, as is done in libp2p.
I added the two lines here, to the one already there

set(LIBP2P_GITHUB_HOST "github.com" CACHE STRING "Host for cpp-libp2p repo (maybe overriden to provide custom ssh key)")
set(SQLITE_GITHUB_HOST "github.com" CACHE STRING "Host for sqlite repo (maybe overriden to provide custom ssh key)")
set(SORALOG_GITHUB_HOST "github.com" CACHE STRING "Host for soralog repo (maybe overriden to provide custom ssh key)")

[kylegranger]

Of course, I'll do a CI run again after this commit.

@kylegranger Could you please merge this PR when you have a chance. So that I'll rebase #35 on master and add key for scale repo in that branch before merging
